Abstract (en)
[origin: US2013086994A1] A flow system based on pulsating mechanism that has better accuracy compared to conventional vortex meters due to the fact that the pulsations generated have increased signal response and lower frequency, both of which are favorable for a high accuracy measurement. Certain embodiments include a housing, a bluff body, an orifice plate, and means for detecting a pulsating frequency of pulsating flow and determining the fluid flow rate based on the detected pulsating frequency. In certain embodiments, the housing can include an outer shell, an inlet, and an outlet.
